I believe the AB040 is "if the HW is Falcon and the CPU is 040 then it
is AB040". After all, the AfterBurner doesn't bring any specific HW
changes apart from the different CPU - the rest is pure original Falcon
HW.

no form, AFAIK, and nothing has ever been planned. ARAnyM is not a
Falcon emulator.

Falcon can have several different bus clock accelerators ranging from 16
up to 25 MHz. That affects the AB040 clock speed directly. So the only
sensible check would be "if the clock speed is higher than 30 MHz bus
clock then it most probably can't be a real HW". This check would
naturally fail on slow hosts...
